VIDEO: WHERE DOES A GIRAFFE GET ITS DRINKING WATER FROM?

This was what we saw when we were in the Singapore Zoo - a giraffe drinking another giraffe's urine. Although it was not a pleasant sight, it sure had created curiosity for me to find out more. And I googled for information regarding the giraffe's strange behaviour. 

There is always something new to learn from the zoo.

And here's the answer found in Wikipedia: "Male giraffes assess female fertility by tasting the female's urine to detect estrus, in a multi-step process known as the Flehmen response." If you want to know more about giraffes, click HERE.
